NVIDIA today brings its next-generation NVIDIA Kepler graphics architecture to the top of the GeForce notebook GPU lineup, with the launch of the NVIDIA GeForce GTX 680M. The fastest, most advanced gaming notebook GPU ever built, the GTX 680M GPU delivers unprecedented performance, incredible power efficiency and the world's most advanced gaming technology.

"The GeForce GTX 680M is the fastest mobile GPU ever, but it's more than just a speed king," said Rene Haas, vice president and general manager of the notebook business unit at NVIDIA. "It also offers an entire arsenal of next-gen gaming technology, along with Optimus technology for extended battery life."

GeForce 600M Series GPUs are built for superior performance and power efficiency. Only GeForce GPUs offer:

Separately, Alienware announced its M17x and M18x gaming laptops will be available with GeForce GTX 680M GPUs in the next couple of weeks.

"The intense focus on performance and technology engineered into the 2GB GDDR5 NVIDIA GeForce GTX 680M is a perfect match for the Alienware M17x and M18x laptops," said Frank Azor, Alienware General Manager. "Whether a single graphics card on the 17x or dual GTX 680M's on the M18x, Alienware owners are going to love having this much power at their fingertips."

The Alienware M17x will be available with a GeForce GTX 680M GPU and NVIDIA Optimus technology or NVIDIA 3D Vision technology. The Alienware M18x notebook will be available with GeForce GTX 680M GPUs in single or SLI configurations before the end of the month.

The GeForce GTX 680M GPU is also available in MSI GT70 notebooks and gaming notebooks from Clevo channel partners such as Ava Direct, Maingear and Origin.

interesting, but what is the power usage and tdp rating on this? on laptops that is a much bigger concern
i wonder how this will stack up against the 7970m
on the desktop the gtx670 was around 20% faster than pitcairns hd7870http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_670/28.html
but on performance per watt it was 10-15% behindhttp://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_670/29.html
so considering this thing is downclocked to match a certain tdp powerconsumption level equal to that of the hd7970m i wonder how the performance stacks up
cant wait for the reviews, as laptops will show a much closer look into efficiency than the desktop reviews did
and offcourse this is exactly were all the effieciency pays off

What is the difference between the: i7-3720QM and the i7 980X (Which is a mobile version, but can't find any I know the i7 920xm, instead how they have bee nable to run the GTX 580m on a desktop CPU? )
